AUTOMATIC SWITCH.

SPECIFICATION forming part of LettersPatent No. 592,043, dated October19, I897.

- Application filed April 24, 1897 Serial No. 633,720. (No model.)

To aZZ whom it may concern:

Be it known that I, GEORGE BANSALL, residing at Lilly, in the county ofCambria and State of Pennsylvania, have invented a new and usefulAutomatic Switch, of which the following is a specification.

My invention relates to a novel arrangement of parts for shifting theswitch-points, and also providing a simple means carried by the car forthis operating mechanism.

The object of my invention is to provide such an arrangement which isautomatic and positive inits action, so that the switch-points can beshifted by the motor of the car. I accomplish this by connecting withthe tie-rod joining the two switch-points bell-crank levers andconnecting with the bell-crank levers pivoted segments which are engagedby suitable means, carried by the car, for depressing them whereby therails are shifted. The segments are arranged in pairs, and apair isplaced on each side of the track, so that a car approaching the switchin either direction can engage with the segments to properly shift thepoints. I also arrange the automatic device carried by the car so thatit can be shifted to either side according to which pair of segments itis desired to operate.

In order that my invention may be fully understood, I will proceed todescribe the same with reference to the accompanying drawings, inwhich-- Figure l is a view showing my invention in practice. Fig. 2 is aplan View of the switchoperating mechanism, and Fig. 3 is a detailelevation of the automatic means for shifting the switch. I

In the said drawin gs,A represents the rails of the main track, A theswitch-rails, and B the switch-points, which are all arranged in theusualway. Oneach side of the main and switch rails I locate themechanism for shifting the switch-points. As it will be seen from thedrawings, the several parts are placed in suitable metalliccasingsO,sunk in the ground so that the removable-metal covers will be flushwith the surface of the street.

The two switch-points are connected by a tie-rod D, having an extensionD and crosshead D which work in the central portion of the metal casingO, and to these cross- -heads I connect the bell-crank levers E byopposite side will be flush with the cover 0.

To further explain the arrangement, referonce is had to Fig. 1, in whichthe switchpoints are set to throw the car onto the switchrails. If thecar is to run on the main rails, the automatic device carried by the caris shifted to depress the segments, which causes the switch-points tomove, and as they are moved the segments on the opposite sides areraised. Should the next car in the same direction have to run on theswitch-rails, the automatic device is shifted to the other side of thecar to depress the segment on that side. It will be seen that theinclined faces 'of the segments on which the automatic device runs areoppositely arranged and are located on each side of the switch, so thatshould acar be traveling in the other direction, either on the mainrails or switch-rails,

.the segments will be in proper position to be engaged by theautomatic-device for shifting the switch-points. 8 5

The automatic device for operating the seg ments, to shift theswitch-points, consists of a pair of wheels or rollers H, carried by ashaft H, supported in a track I, carried beneath the car-platform. Theshaft is adapted 0 to be shifted in the bracket so that either se -mentcan be engaged, and the means for shifting the shaft consists of agrooved pulley J, carried on a shaft or rod K, journaled to the front ofthe car, and a cord or rope L, 9 5 connected near each end of the shaftand having its middle portion passedaround the grooved pulley. The upperend of the shaft is provided with a handle M, which slides on a segmentM. This handle is limited in its movement on the segment by the pins N,placed at each end thereof. The operation of this part of my device willbe readily understood. The wheels or rollers run normally on the groundon each side of the track, and are adapted to run on the inclined faceof the segments when it is desired to shift the switchpoints.

From the foregoing it will be seen that I have provided a simplearrangement for shifting ments adapted to be engaged by means carried onthe car whereby the switch-points are shifted said means consisting of apair of wheels mounted on a shaft which is carried by a bracket, saidshaft having means in 0011- nection with it for shifting it laterally inthe bracket consisting of a pulley carried 011 the shaft or rod providedwith the operatinghandle at one end and a rope or cord connected withthe shaft near each end thereof and having its middle portion passedaround the pulley, substantially as shown and described.

GEORGE BANSALL.
